抄録
<tt>In order to compare the behavioural responses to humans of Jersey cows between different stockpersons, the cows were observed for 3 types of behaviour: stepping, kicking and lifting associated with the hind foot during milking. Milking was performed by the stockpersons with two different skill levels, i. e. students with little experience and teachers with much experience. Cow temperament was assessed by each reaction in behavioural tests (flight response, touch, novel object and conflict) indicative of fear response. The number of steps made by the cows prior to milking in the morning and evening was significantly different between the students (7.1 </tt>±<tt>7.1 and 7.9 </tt>±<tt>7.4) and the teachers (3.8 </tt>±<tt>4.4 and 3.6 </tt>±<tt>3.2)(P<0.05). In contract, the number of lifts of the cows during milking in the morning and evening was significantly less in the students (0.5 </tt>±<tt>1.0 and 0.7 </tt>±<tt>1.0) than the teachers (1.2 </tt>±<tt>1.9 and 2.9 </tt>±<tt>3.4) (P<0.05). The number of kicks made by the cows before the student milked was negatively correlated with the frequency of touching toward the object in the novel object test (rs = -0.892, P < 0.05). The number of lifts performed by the cows while the student was milking was negatively correlated with feeding latency in the conflict test (rs = -0.926, P < 0.05). In conclusion, hind foot-related behaviour of the Jersey cows during milking was affected by the stockpersons, indicating the possible effects of their skill and/or novelty. However, the </tt><tt>relation of the behaviour with fear responses was not verified. </tt>
